I'd take two RM30C w/ a New Orig Sub w/ amp anyday. I owned both speakers. The main deficiency is the old BG ribbon. Great for its time, but Brian is always forging ahead. It's an oddity now at this date. On the other hand, it's a killer price including shipping. If you could sell the BG ribbon you could replace it with 6x new 8" ribbons for whatever Brian wants for them. (new Xo's must also be purchased & installed.) Then you'd have something interesting. But I'd still prefer the first rig I mentioned above because you can eliminate a room mode with the sub amp's parametric EQ. Plus hugely better ergos.
